Implementa el subsistema completo de background jobs para apps Go en el dominio infra. 9 funciones + 3 tipos + 17 tests, todos pasando. - Tipos: Job (product), JobQueue (product), JobStatus (sum) con JobHandler, EnqueueOption y WorkerOption usando functional options pattern - job_queue_create: CREATE TABLE + indices + WAL mode - job_enqueue: INSERT con UUID (github.com/google/uuid), WithPriority/WithScheduledAt/WithMaxAttempts - job_dequeue: SELECT+UPDATE atomico en transaccion exclusiva, filtro por jobTypes - job_complete / job_fail: transiciones de estado; fail → dead cuando attempts >= max_attempts - job_status_summary: pura, formatea conteo de jobs por estado - job_worker: poll loop bloqueante, context-cancelable, graceful shutdown - job_worker_pool: N workers con golang.org/x/sync/errgroup - job_cleanup: DELETE jobs terminales mas viejos que olderThan Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

## Ejemplo
|
|
|
|
```go
|
|
// Limpiar jobs terminados hace mas de 7 dias
|
|
n, err := JobCleanup(q, 7*24*time.Hour)
|
|
fmt.Printf("eliminados: %d jobs\n", n)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Solo elimina jobs en estados terminales: completed, failed, dead. Los jobs pending y running nunca se eliminan. El cutoff se calcula en UTC. Llamar periodicamente con CronTicker u otro scheduler para mantener la tabla compacta.
